Gen Petraeus insists he will not be bound by Obama's Afghan exit date

The US army general, David Petraeus, made clear today that he would not be bound by Barack Obama's promise to start withdrawing US troops from Afghanistan by July next year.
In his first interview since taking command of Nato troops in the country less than two months ago, the top general said he could foresee circumstances where conditions would make it impossible for him to recommend a reduction in forces.
